EDWARD J. MCGUIRE, OF LUMBERTON, NORTH CAROLINA.

LUBRICATOR.

Specification of Letters Patent.

Patented Nov. 17, 1908.

Application filed April 11, 1908. Serial No. 426,515.

To all whom it may concern:

Be it known that I, EDWARD J. MCGUIRE, a citizen of the United States,residing at Lumberton, in the county of Robeson and State of NorthCarolina, have invented new and useful Improvements in Lubricators, ofwhich the following is a specification.

This invention relates to improvements in oiling devices of that classknown as sightfeed and by which the supply of the lubricant can beaccurately regulated and wherein the parts are adjustable and readilyoperative to cut oif the oil or to supply the required quantity of oil,according as the engine or other part or mechanism to be lubricated mayrequire.

The object of the present invention is to simplify oiling devices andrender them efi'ective in their operation as well as to combine in onedevice oil filtering and feeding means of an efficient character, theseveral parts of the oiling device orlubricator being readily associatedor separated for convenience in manufacture and application and cleaningand repair purposes.

The invention consists in the construction and arrangement of the partswhich will be more fully hereinafter specified.

In the drawing: Figure 1 is a transverse vertical section of an oilingdevice or lubricator embodying the features of the invention. Fig. 2 isa top plan view of the same. Fig. 3 is a horizontal section on the line-33, Fi 1.

gimilar characters of reference are employed to indicate correspondingparts in the several views.

The numeral 1 designates an oil cup of any suitable construction, butpreferably comprising a transparent body or cylinder 2 with an upperclosing cap or head 3 fitted thereover and a lower or base cap 4.Suitable packing means will be interposed be tween the terminals of thebody or cylinder 2 and the caps for a purpose which will be readilyunderstood. Rising from the center of the base cap 4 and preferablyformed therewith is a feed tube 5 having a lower extension or outletnozzle 6 depending from the center of the cap 4.: and an upperscrewthreaded extremity 7 over which the cap'3 is fitted, the said cap 3being held down in place on the body or cylinder 2 by a clamping memberhaving an inner extremity 8 resting on the top of the said cap andengaging the screw-threaded extremity 7, and also provided with anoutwardly projecting handle 9 by means of which the said clamping membermay be operated. Over the inner extremity 8 of the clamping member a nut10 is applied to the screw-threaded extremity 7 of the feed tube andserves as a set device or element to prevent loosening of the parts.

The feed tube 5 has a bore 11 extending centrally therethrough andformed with an upper screw threaded portion 12 and a lower constrictedcontinuation 13 projecting through the nozzle 6. The upper extremity ofthe constricted continuation 13 of the bore is adapted to be engaged bya needle valve 1% continuous with a rod or stem 15 which graduallyincreases in diameter to a maximum diametrically enlarged portion 16which is screw-threaded to engage the screwthreads 12 in the upper partof the bore 11. The stem or rod 15 continues above the upper terminal ofthe feed tube 5 and has an adjusting lever 17 movably connected theretoand adapted to engage notches or peripheral seats 18 formed in the cap3, as clearly shown by Fig. 2. By turning the rod or stem 15 through themedium of the lever 17, the needle valve 14 may be raised or lowered tocontrol the feed of the oil through the nozzle 6. The feed tube 5 isalso provided with a plurality of feed openings 19 communicating withthe upper portion of the feed cup and the bore 11 and through which theoil passes from the cup into the bore of the feed tube. The nozzle 6 isexternally screw-threaded as at 20 and thereover is applied the upperend of a combined sighting and securing member 21 having a lowerexternally screw-threaded tubular component 22 which is shouldered forconvenience in applying the oiling device or lubricator to an engine ormechanical element adapted to be lubricated, and with which it isdesired that the lubricator perform its function. The member 21 adjacentto the lower outlet terminal of the nozzle 6 has a glass cylinder 23fitted therein and exposed by opposite openings 24 so that the oildripping from the nozzle downwardly to the component 22 may be readilyseen from the exterior of the lubricator and serve as means for guidingan operator in determining the amount of oil fed to the engine ormechanical element lubricated.

An oil supply tube 25 is formed continuous with or as a part of the feedtube 5 and terminates adjacent to the bottom of the cup, the upperextremity 26 of this supply tube being laterally deflected and projectedupwardly through and extended above the cap 3, the clamping member 8serving as a cover means for the upper inlet end of this supply tube andhaving a handle 9 broad enough to perform the function of a closingdevice. WVhile the clamping device is effective in holding the cap 3down in place when engaged by the nut 10, it will be understood thatthis function is secondary to the more important service as a closingmeans for the upper inlet extremity of the supply tube 25. Suitablybrazed on or otherwise secured to and surrounding the feed and supplytubes 5 and 25 below the lowermost feed opening 19 is a canopy ordefiector 27 which is of less diameter than the interior of the cup, buthas sufficient outward extent to serve the purpose for which it has beendevised. A tight joint is formed between the canopy or deflector 27 andthe feed tube and supply tube, and said defiector is imperforate and hasan upper downwardly inclined surface 28.

In preparing the oiling device or lubricator for service a quantity ofwater is disposed therein and extends up over the canopy or deflector27. A. supply of oil is then introduced through the tube 25 and owing toits lightness as compared with the water, passes upward or filtersthrough the latter and is sustained on the surface of column of water,the oil being delivered within the cup near the base of the latter andbeing freed of impurities or sediment such as grit in fine particleswhen passing upwardly through the column of water. If the oil is notfully freed from sediment or grit when passing upwardly through thecolumn of water, such sediment or grit will gravitate from the oil ontothe upper inclined surface 28 of the canopy or deflector 27 and from thelatter will gradually work downward into the column of water and bedeposited against the base cap 4. The cup may be cleaned or relieved ofsediment as well as the column of water through the medium of a draincock 29 secured to the cap 4 as shown by Fig. 1. The oil after it hasbeen cleansed or filtered passes through the openings 19 into the bore11 of the feed tube 5 and from the said bore is fed through the nozzle 6in accordance with the adjustment of the needle valve 14.

The oil in filtering upwardly through the column of water is forced topass around and over the periphery of the canopy or deflector 27 in viewof the fact that there are no openings in the said canopy or deflector,and hence the oil will become more thoroughly filtered or cleansed.

The improved oiling device or lubricator will be found especiallyadvantageous in its operation, and such changes as to proportions,dimensions and minor details may be adopted as fairly fall within thescope of the invention and to adapt the lubricator for application todifferent mechanisms.

Having thus fully described the invention, what is claimed as new, is:
